WRITING TELEGRAPH.

(Fiom the Commission Agent) An Apparatus bas at length been perfected for transmitting telegrams in such a manner that tbe printing apparatus at the receiving office shall record the message in a fac-Bimile of tbe sender's band. The system is capable of transmitting* over a siogle wire from 50 to 150 words per minute, against a possible 30 to 40 by the Morse system, which is \ that now in common use. By this system a person's own handwriting is transmitted by telegraph, the same as though sent by mail, and, in brief, simply accomplishes letter writing by telegraph. In order to render its operation fully understood it may be described as follows; — First the sender of a message writes it upon ordinary white paper ; the

written message is then laid upon a metallic plate and pissed between two rollers, with the effect of transferring the copy to the plate, which may be donß any time within 10 hours 'after writing. Then the plate containing the copy is placed upon a semi-cylin-drical holder which -traverses a little track, and the iastrament is set in motion, the whole operation up to this point having been accomplished in less time (had t takes to write it ; whereas, by the Morse system, quite a number of minutes elapse before the message reaches the operator. The metallic plate is a conductor of electricity, while the lines of writing are nonconductors. Over the cylindrical plate are carried metallic points upon revolving arms ; whenever the point is upon the metallic surface, the electric current passes through the wire ; the instant the point touches a line of writing, the connection is broken and a dot is made upon chemically prepared paper, placed upon, a similar instrument at the receiving point. The two instruments operate synchronously, i.e., the moment a point is passing over the surface of one instrument, it is followed exactly by the point on the other instrument. An ingenious mechanical arrangement perfects the transmitting powers and prevents the possibility of ooe instrument gaining over the other; At the same time the points are moving over its surface, the plate is moving slowly horizontally, so that the entire surface is traversed. The transferred message is, of course, in reverse, but is brought straight by running the receiving instrument in as opposite direction. Each instrument is fitted to either receive or transmit at pleasure. Thie rate of, speed varies according to ; the closenes of the writing ; the points traversing the entire surface of the copy, it is immaterial as to the number of words, only the apace they occupy requiring a given time to be gone over. Ordinary writing will be transmitted at the rate of from 50 to 100 words per minute. The meesaage as received is ready at once for delivery, and appears, in close dark blue dotted lines on white paper. There is no loss of time in counting words at the sending station, as is now the case, nor delay in getting to the hand of the operator ; but in a quarter of a minute's time of its being received it is speeding on its way to its destination, and automatically preparing itself for delivery. The wonderful facilities of the system render it peculiarly adapted to a large and hurried business. It is the fruit of many years close ap. plication, hence the perfection with which it makes its appearance.
